--- Comment #5 from Stephan Beyer <s-beyer at gmx dot net> ---
It crashes on run-time.

I have absolutely no experience using extended asm syntax but I
guess g++ relies on the constraints for its optimization, so I
guess the constraints are wrong.

I will port the code to use the macro from cpuid.h and close the
issue if there are no more crashes.

Thank you.
